Witrynaimpurities had been identified in certain technical materials that would have been overlooked in the present Tier-2 equivalence evaluation. This is due to the fact that certain impurities meeting the criteria for relevance do not produce observable effects in acute, short term toxicity test protocols. Such an example is fluazinam TC WitrynaActive substances often contain impurities which originate from manufacturing. According to the definition of Regulation ( EU ) No 283/2013, impurities in the technical active substance are considered relevant if they are particularly undesirable because of their toxicological, ecotoxicological or environmental properties. rete sport in diretta twitch https://austexcommunity.com
